Abstract: A system for distributing successively formed groups of glass gobs from a feeder bowl to the several individual sections of a Hartford I.S. type glassware forming machine includes a single scoop for each gob in the group, and mechanism for rotating the scoops between successive positions wherein each is aligned with a chute associated with a particular mold cavity in each machine section. A "double-gob" installation is described and the two scoops have associated annular spur gears which are driven in unison by a reciprocable rack gear through a predetermined schedule of angular displacement to successively align the two scoops with several sets of paired chutes according to a particular order and to then repeat this schedule. A cam follower connected to the rack gear causes programmed movement thereof in response to rotation of a cam having lobes of predetermined height to produce the predetermined schedule of angular displacements of the scoops.

Abstract: A glassware forming machine has mold holder arms pivotally mounted on a common hinge pin, and a conventional rock shaft and crank opens and closes each of these arms through a short link pivotally connecting the arm to the crank. The angular displacements of these arms are limited by the geometry of a conventional glassware forming machine, and in order to blow larger size ware the present invention contemplates subjecting the split molds, which are pivotally carried on these arms, to a cocking motion as the arms are opened. An interconnecting link acts on the molds and operates off the crank. The interconnecting link operates when the mold holder arms are open, but does not interfere with the normal mold closing motion. An alternative configuration is shown for the blank mold side of an I. S. machine to increase the clearance for the neck ring arm during revert motion, and to allow longer parisons to be reverted.
